![]() ![]() Barometer - A barometer measures the air pressure and whether it is rising or falling.Anemometer - An anemometer measures the speed of the wind.Rain gauge - A rain gauge is tool used to measure the amount of rainfall.Satellites - Satellites can be used to see cloud formations over large areas of the Earth.This can help meteorologists in providing severe storm warnings. Doppler radar - Doppler radar is a special kind of radar that can determine the rate of precipitation (rain, hail, snow) as well as wind speed and direction. ![]() Some of the tools meteorologists use are described below. There can be large differences between the temperature and dew point on each side of the dry line.Ī lot of technology goes into measuring and predicting the weather. Dry line - A dry line is a boundary separating a dry air mass from a warm air mass.Occluded Front - An occluded front occurs when a cold air mass takes over a warm air mass.Stationary fronts can bring long periods of rain. Stationary Front - A stationary front is a front that stays in one place for a long period of time.Warm fronts tend to move more slowly than cold fronts. Warm Front - A front where a warm air mass is replacing a cold air mass.Cold fronts can cause a narrow line of storms and can cause the weather to change rapidly. When a cold front passes through, the temperature will drop. Cold Front - A front where a cold air mass is replacing a warm air mass.It is where these two different masses of air meet that most storms form. The boundary between high and low pressure systems is called a weather front. On a weather map a low pressure system is shown by a red L. This is because low pressure systems generally attract warm and moist air. Low pressure system - A low pressure system generally means rainy or cloudy weather. On a weather map a high pressure system is shown by a blue H. High pressure system - A high pressure system generally means good weather because it attracts cool and dry air. Knowing areas of high and low air pressure is important to predicting the weather because differences in air pressure causes wind to form. In order to forecast the weather, they study high and low pressure systems and the boundaries between them called weather fronts. Meteorologists measure and study many aspects of the Earth's atmosphere. For this reason, the predictions are not 100% accurate. However, there are a lot of variables that goes into predicting the weather. By studying the Earth's atmosphere, meteorologists are able to predict what the weather will be. Scientists who study the atmosphere are called meteorologists. Meteorology is the study of the Earth's atmosphere. Although it may sometimes seem like weather forecasters are just guessing, there is a lot of science that goes into predicting the weather. We want to know how warm to dress, if we should bring an umbrella, or if it will be a good day for a picnic. We all want to know what the weather is going to be like. ![]()
